Its more intention revealing, and if we're interested in the odd cases
where this may end up truncating we can do debug checks at one
centralized place.
Motivation, of all the container builds, fedora rawhide started
complaining of:
util/machine.c: In function ‘machine__create_modules’:
util/machine.c:1419:50: error: ‘%s’ directive output may be truncated writing up to 255 bytes into a region of size between 0 and 4095 [-Werror=format-truncation=]
1419 | snprintf(path, sizeof(path), "%s/%s", dir_name, dent->d_name);
| ^~
In file included from /usr/include/stdio.h:894,
from util/branch.h:9,
from util/callchain.h:8,
from util/machine.c:7:
In function ‘snprintf’,
inlined from ‘maps__set_modules_path_dir’ at util/machine.c:1419:3,

There are other places where we should use path__join(), but lets get rid of
this one first.
